Okay, so I went and took Daisy to the vet at schoool, (recently graduated vets work there, so they give the college students a discount) for a recheck in urine, (it went down a little- lingering at 7.5 from 8.5 yay!) and the vet (who's been a vet for about 5 years) said that she thought Daisy had "partial dwarfism". She says it's a genetic disorder that some puppies are born with. She says that most responsible breeders euthanize these pups within the first couple of days. Not sure what I can do with that piece of info, but okay.
She then goes on to say that people are wanting to breed them more and more- get a Shih Tzu with a doxie or corgi body. What was once a genetic defect now people are actually breeding INTO. Daisy wasn't fixed when we got her, so she may have been one of the 'test' dogs. She said that Daisy is only a "partial" dwarf since it's only her front legs that's the problem. She says that dwarf dogs have a whole strew of problems, including hypothyroid and cushings. Lovely!
I always thought that Daisy was just not a purebred shih Tzu but maybe had some Jack Russel (since she's really skinny and hyper- sorry Jennie!) or Boston Terrier somewhere very far down the road. I'll post pictures of her, but I have been reading, and the classic symptom is "Homozygous dogs are all reported to have abnormal skeletons - dwarfism in the sense of front shoulders lower than rear - a sort of 'bulldog' appearance."

That's definitely Daisy!! Oh well, I don't care where I got her or if she has some faults, but I love her just the same- she may cost me more, but I love her just the same! [

Any thoughts? I know that this is a known disease in GSDs, but I didn't know it could happen with smaller dogs.
Her "broad shoulders"
and her mis-aligned body
